In these times of instant gratification and easy 'availability', find out if his roving eye has been indulging in some bad old infidelity

He’s perpetually “busy”: Busy at work, busy after work, busy on the phone, busy on the computer. Is he so swamped that he’s left with barely enough time for you? This is your first clue.

Too anxious to erase: Does he grab his phone the second it beeps lest you catch a glimpse of the person contacting him, grin to himself like a hormonal fool while texting/emailing and talk in syllables/whispers/a code language? And yes, does he press the erase button soon after? Ladies and gentlemen, we’ve got a winner.

Female trail: Her lipstick on his shirt collar, her perfume on his skin, her hickeys branding him, her hair in the car seat (ugh!) — some of the oldest signs in the book of cheating. Even one of the above is cause enough for concern.

Lately late: Another tell-late sign that he could be cheating on you. If he seems to be spending all his waking hours at work, if he’s been doing more overtime than ever, if he’s been taking off on 'business trips' by the dozen, that’s trouble with a capital T.

No more meal company: The family that eats together stays together. If you’ve been having dinner — and even lunch on weekends — alone for a while now, it’s time to do some sniffing around. Fishy business.

Spring to his step: Despite him being super-busy and super-late all the time, is he glowing with contentment (the way he used to in the initial phase of your relationship)? Does he have a spring to his step, making him suddenly seem younger and boyish? Affirmative? Negative.

Clotheshorse alert: Has the man who didn’t care less about his clothes become fashion-savvy overnight? The man who once happily let you do his shopping developed a voice? Trendy clothes maketh a cheater.

He’s gym-happy: He’s suddenly all gung-ho about being fit, and talks about wanting to bulk up and/or lose that beer belly. He has recently taken the initiative to enroll in a gym or play a sport all by himself, despite the fact that you’ve been nagging him forever to do so.

Presents much: Another age-old sign is of cheaters trying to enthusiastically absolve their guilt by showering you with gifts. Without any occasion. Especially if you received presents once in a blue moon before.

In the red: Does he throw you the “No more moolah, dahlin'” look/line all the time now? Doesn’t take a rocket scientist to figure where all that dough’s been going.
